24 Sussex Drive is the official residence of the Prime Minister of Canada.
The is 148-year-old building, originally called Gorffwysfa, was built between 1866 and 1868 by Joseph Merrill Currier, it has been the official home of the Prime Minister of Canada since 1951.
Louis St. Laurent was the first Prime Minister to take up residence at 24 Sussex Drive.
24 Sussex is used almost exclusively as a place of residence and not government business.
The building has several problems. The wiring in the walls is 60-years-old, there is mold in the pool building and structural problems.
The National Capital Commission (NCC), the Crown corporation that oversees federally owned lands and buildings around Ottawa (the capital region), stated in 2011 the repairs would take more than a year to complete and could cost up to $10 million.
Prime Minister Justin Trudeau does not live at 24 Sussex Drive but rather lives at Rideau Cottage.
